Product Description:

The MDD041A-N-100-N2K-050FA1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Designed for pairing with digital drive controllers, it transforms controlled current from an inverter into precise rotary motion. This allows automated pick-and-place arms, small conveyors, or measuring spindles to index and hold positions with repeatable accuracy. The motor is intended for precise industrial motion rather than general-purpose constant-speed duty.

During continuous operation, the rotor sustains 0.64 Nm of torque at standstill, and the mechanical design supports a nominal speed of 10,000 rpm for fast cyclic moves. A standard balancing grade limits residual vibration, while the 50 mm centering diameter positions the flange concentrically on mounting fixtures. Cables exit on side A, and a single sealed connector carries both power and feedback to minimize cabinet openings. Position data is delivered by an integrated absolute encoder, and supplementary velocity signals are available through resolver feedback when required by the drive. The aluminum housing follows the series standard pattern, with frame size 041 and motor length code A for a compact envelope on space-limited axes.

A blocking brake rated at 1.2 Nm keeps the shaft locked when power is removed, which helps prevent back-driving on vertically loaded installations. Torque is transferred through a plain shaft that has no keyway, which helps reduce runout in precision couplings. Because the motor is supplied without a shaft seal, it should be placed in clean or protected zones to reduce contaminant entry at the bearing face. The shaft end follows the standard format with no opposite-side extension, and the unit is classified as a motor for digital drive controllers for direct use with Indramat drive packs that command current, velocity, and position loops without additional interface hardware.
